Attr Object
Definition and Usage
The isId property returns true if an attribute is known to be of type ID (e.g. contains an identifier for its owner element), otherwise it returns false.
Syntax
attrObject.isId
Example
The following code fragment loads "books.xml" into xmlDoc using loadXMLDoc() and returns whether the category attribute is an ID attribute of the <book> element:
Example
xmlDoc=loadXMLDoc("books.xml");
x=xmlDoc.getElementsByTagName('book');
for(i=0;i<x.length;i++)
{
document.write(x.item(i).attributes[0].isId);
document.write("
");
}
x=xmlDoc.getElementsByTagName('book');
for(i=0;i<x.length;i++)
{
document.write(x.item(i).attributes[0].isId);
document.write("
");
}
The output of the code above will be:
false
